Angola, located in Central Africa, has around 320,000 (270,000-380,000) people living with human immunodeficiency virus (HIV)/AIDS, equivalent to 1% of the country's population at the end of 2021. A previous study conducted in 2012, using Angolan samples collected between 2008 and 2010 revealed a high prevalence of HIV-1 recombinants, around 42% of sequences, with 21% showing the same UH profile in partial pol region which were grouped into a monophyletic cluster with high bootstrap support. Thus, the objective of the present work was to obtain complete genomes of those sequences and characterize them, aiming at a description of a new circulating recombinant form (CRF).

The parasite, which lives in the large intestine and in other organs, can lead to serious infections that may culminate in death. Information about human balantidiasis is generally still very scanty.

- Previous studies identified a significant diversity of HIV-1 in Cabo Verde, with 5.2% classified as AU subtypes, prompting further investigation into these sequences.
- The research involved analyzing genomic DNA from seven HIV-1 AU-infected individuals, using nested-PCR to amplify their genomes and creating phylogenetic trees to classify the samples.
- The study successfully amplified complete genomes for two samples, classifying them as a new sub-subtype A, and emphasizing the need for ongoing surveillance in regions with high HIV diversity.
